A simple, green method was developed for the synthesis of gold and silver nanoparticles by using polysaccharides as reducing/stabilizing agents. The obtained positively charged chitosan-stabilized gold nanoparticles and negatively charged heparin-stabilized silver nanoparticles were characterized with UV-vis spectroscopy and transmission electron microscopy. The results illustrated the formation of gold and silver nanoparticles inside the nanoscopic polysaccharide templates. Moreover, the morphology and size distribution of prepared gold and silver nanoparticles varied with the concentration of both the polysaccharides and the precursor metal salts.
开发了一种简单、绿色的方法，以多糖作为还原/稳定剂来合成金和银纳米颗粒。通过紫外可见光谱和透射电子显微镜对所获得的带正电荷的壳聚糖稳定的金纳米颗粒和带负电荷的肝素稳定的银纳米颗粒进行了表征。结果表明在纳米级多糖模板内形成了金和银纳米颗粒。此外，所制备的金和银纳米颗粒的形态和尺寸分布随多糖和前体金属盐的浓度而变化。
